What is WiFi Technology & How Does It Work?


                     Wi-Fi is a popular wireless networking technology. Wi-Fi stands for “wireless fidelity”. Wi-Fi was invented by NCR Corporation/AT&T in the Netherlands in 1991. By using this technology we can exchange information between two or more devices.

 Wi-Fi has been developed for mobile computing devices, such as laptops, but it is now extensively using for mobile applications and consumer electronics like televisions, DVD players, and digital cameras.

 There should be two possibilities in communicating with the Wi-Fi connection that may be through an access point to the client connection or client to client connection. Wi-Fi is one type of wireless technology.

 It is commonly called a wireless LAN (local area network). WiFi technology allows local area networks to operate without cable and wiring. It is making a popular choice for home and business networks. A computer’s wireless adaptor transfers the data into a radio signal and transfers the data into an antenna for users.

WiFi Technology Working Principle:


                                    Wi-Fi is a high-speed internet connection and network connection without the use of any cables or wires. The wireless network is operating three essential elements that are radio signals, antenna, and router. The radio waves are keys that make Wi-Fi networking possible. The computers and cell phones are ready with Wi-Fi cards. Wi-Fi compatibility has been using a new creation to constituent within the ground connected with community network

The actual broadcast is connected in sequence in fact it is completed by way of stereo system surf as well as the worth of wires with the monitor to classification prone. Wi-Fi allows the person in order to get access to the web any place in the actually provided area. You can now generate a system within Resorts, library, schools, colleges, campus, personal institutes, as well as espresso stores as well as on the open public spot to help to make your company much more lucrative as well as interact with their own customer whenever.

                                      Wi-Fi compatibility can make surf with stare to the company using their inspiring cable television much a smaller amount force down. The radio signals are transmitted from antennas and routers that signals are picked up by Wi-Fi receivers, such as computers and cell phones that are ready with Wi-Fi cards. Whenever the computer receives the signals within the range of 100-150 feet for the router it connects the device immediately.

       Security: 


                Security is an important element in Wi-Fi technology. Security is our personal decision but having a wireless connection we should pay attention to protect our private details. We can connect easily to unsecured wireless routers. The problem is anyone is connected to your wireless router using the data like download games, download apps and planning terrorist activities, shirring illegal music and movie files, etc. So it is necessary to provide security to the wireless technologies based devices.

   WiFi Technology Advantages & Disadvantages:


     The advantages of WiFi technology include the following.

                    
  • A wireless laptop can be moved from one place to another place
  • Wi-Fi network communication devices without wire can reduce the cost of wires.
  • Wi-Fi setup and configuration is easy than the cabling process
  • It is completely safe and it will not interfere with any network
  • We can also connect internet via hot spots
  • We can connect internet wirelessly
The disadvantages of WiFi technology include the following.

  • Wi-Fi generates radiations which can harm the human health
  • We must disconnect the Wi-Fi connection whenever we are not using the server
  • There are some limits to transfer the data, we cant able to transfer the data for long-distance
  • Wi-Fi implementation is very expensive when compared to the wired connection

Applications of WiFi Technology:


The applications of WiFi include the following.

  • Mobile applications
  • Business applications
  • Home applications
  • Computerized application
  • Automotive segment
  • Browsing internet
  • Video conference

      (WiFi) Wireless Networking - Advantages and Disadvantages                           The popularity of wireless LANs is a testament primarily to their convenience, cost efficiency, and ease of integration with other networks and network components. The majority of computers sold to consumers today come equipped with all necessary wireless LAN technology.                  Advantages of Wifi : Convenience                The wireless nature of such networks allow users to access network resources from nearly any convenient location within their primary networking environment (a home or office). With the increasing saturation of laptop-style computers, this is particularly relevant. Mobility           With the emergence of public wireless networks, users can access the internet even outside the...

Diode: Definition, Symbol, and Types of Diodes

  What is a Diode? A  diode  is defined as a two-terminal electronic component that only conducts current in one direction (so long as it is operated within a specified voltage level). An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction.              Although in the real world, diodes can not achieve zero or infinite resistance. Instead, a diode will have negligible resistance in one direction (to allow current flow), and very high resistance in the reverse direction (to prevent current flow). A diode is effectively like a valve for an electrical circuit.             Semiconductor diodes are the most common type of diode. These diodes begin conducting electricity only if a certain threshold voltage is present in the forward direction (i.e. the “low resistance” direction). The diode is said to be “ forward biased ” when conducting cu...

L                             Light Emitting Diode                     Light-emitting diodes, or LEDs, are widely used as a standard source of light in electrical equipment. It has a wide array of applications ranging from your mobile phone to large advertising billboards. They find applications in devices for showing what the time is and for displaying different types of data. In this post, the main focus would be on learning a lot about LEDs, such as its operations and functions. What is  light emitting diode:                    A light releasing diode is an electric component that emits light when the electric current flows through it. It is a light source based on semiconductors. When current passes through the LED, the electrons recombine with holes emitting light in the process. It is a specific type of...
